It ivi!! ne umm-Stond that the refrigerating coils may be direct-ly inserted into the cooling chamber or other chamber of the refrigerator but in the present instance I have shown the saine as contained within a' suitable brine tank S whichis fastened at. its u per end to a horizontal head Yblock 35 w ich is in turn secured by means of bolts 36 to the underside ol' the base plate 7. The coils 9 are held supported within the brine tank in suitable manner as by means of the straps 3T secured to the block 35. These coils are also held in position byu vertical straps 3S. In order to carry away any drip from the top of the base plate 7 adjacent the expansion valve, I provide a vertical drip pipe 39 which extends into if vertical pipe 40 passing: through the brine tank with the result that the drip is conducted to a point below such tank.

In this manner and by these means I produce a refrigcrating apparatus provided with a. single tank having,r all ofthe functions ofthe double tank or cylinder type and provide a single cylinder construction very compact and of comparatively small compass considering the capacity thereof.

I claim: i'

1. In a refrigerating apparatus the combination of a combined pump chamber and condenser chamber, a pump therein. coudenser coils located at the upper portion of the chamber, cooling coils located at an intermediate portion thereof and substantially at the same level as the pump, an expansion Valve communicating with the bot tom of the chamber. and reztrigerating coils communicating with the expansion valve and with the pump.

2. In a. refrigerating apparatus the combination of a combined pump chamber and condenser chamber, a pump therein. condenser coils located at the upper portion of the chamber. cooling coils located at an intermediate portion thereof and substantially at the same level as the pump. a drip pan arranged below the condenser coils and having an outlet communicatingwith the chamber near its bottom. an expansion valve comA munie-ating with the bottom of the chamber, and retriaferatinar coils communicatingr with the expansion valve and with thc pump.

3. In a refrigerating apparatus the combination of a. combined pump chamber and condenser chamber. a pump therein. condenser coils located at the upper portion o't the chamber, cooling coils located at an intermediate portion thereof and substantially atA the same level as the pump, a drin pan which is arranged below and supports the condenser coils such pan having a bottomv outlet for the refrigerant, a pipe communieating with such outlet and extendinglo near the bottom of the chamber. an expansion valve communicating with the bottom of the chamber, and refrigerating coils communicating with the expansion rali-e and with the pump. the inlet. pipe of the. condenser coil passinf.l upwardly through the refrigerant pipe and connected with the condenser coils.

5. In a refrigeratiingr apparatus. the combination of a pump chamber. a pump in said chamber. the chamber containing;r a body of oil in the zone of the pump. cooling coils also located in said body oi oil. condenser meuns. means for conducting theJ liquid refrigerant as condensed by the con denser means to the bottom of said chamber and under the oil. an expansion valve communicating with the bottom of the chamber. and refrigerating.r coils communicating,r with the expansion valve and with the pump.

6. In a refrigerating apparatus, the combination of a pump, a chamber containing a body of oil. condenser means1 a pipe extending through said body of oil for conl ducting the liquid refrigerant as condensed by the condenser means to the bottom of the chamber and under the oil', an expansion valve communicating' with the bottom of the chamber. and a refrigerating coil communirating with the expansion valve and with the pump.

7. In a refrigerating apparatus, a tank having a pump chamber. a pump mounted in said chamber and adapted to discharge refrigerant therein. means at the upper portion of said chamber for condensing said refrigerant, a drip pan in said chamber intermediate the condensing means and the pump for receiving.T the condensed refrigerwith said pump and said chamber.

9. In a retrigerating apparatus. a tank having a pump chamber. a pump mounted in said chamber and .adapted to discharge re,- frigerant therein. said pump having au upwardly -extending outlet opening. means at; the upper portion of said chamber for condensing said refrigerant, a drip pan in said chamber intermediate the condensing means and the pump for receiving the condensed refrigerant and for forming a. baille for the gas from the pump outlet. and refrigerating coils communicating with said pump and said chamber.
